Assessment of Radiofrequency-Induced Heating in the Magnetic Resonance Environment for Multi-Configuration Passive Medical Devices; Guidance for Industry and Food and Drug Administration Staff; Availability

Riepilogo

The Food and Drug Administration (FDA or Agency) is announcing the availability of the guidance entitled "Assessment of Radiofrequency-Induced Heating in the Magnetic Resonance (MR) Environment for Multi-Configuration Passive Medical Devices." FDA is confronted with an increasing number of premarket submissions that include an MR Conditional labeling claim for multiconfiguration passive medical devices. The assessment of radiofrequency (RF)-induced heating of such devices, typically comprised of many parts, strongly depends on the specific device geometry and can therefore lead to a prohibitively large number of test cases. This guidance provides an approach to reduce the number of possible device configurations to a manageable number, and it provides guidance on how to assess the RF-induced device heating for an individual configuration.
